' T 0 all whom t may concern Be it known that we, HENRY 1V. WiN'rER andEDWIN W. SMITH, citizens of the United States, residing'at Methuen, inthe county of Essex and Commonwealth of Massachusetts, and Beverly, inthe county of Essex and Commonwealth of Massachusetts, respectively,have invented certain new anduseful` Improvements in Sole-PreparingMachines; and We do hereby declare thc-following to be a full,clear,'and exact description of the invention, vsuch as will enableothers skilled in the art to which itappertains to make and use thesame.

This invention relates to sole-preparing machines and more particularlyto such machines for performing one or all of the operations ofrounding, channeling, and groovingr which are commonly performed upon soes or sole-blanks to fit them for the operation of sewing them to shoeuppers.

'One object of the invention is to produce a machine in which thevarious operations are performed automatically, particularly withrespect to the introduction and removal of the sole-blanks,.so that theattention of an operator may be necessary only in supplying blanks tothe container or magazine with which the machine is provided.

Another object ofthe invention is to provide Aa machine of t-hecharacter described with-novel and improved mechanism for producing therelative movements of the sole-clamping devices and the tools, by

.which the point of en agement of the tools.

with the sole is trans erred around the periphery of the sole.

To the foregoing ends the features of the invention contemplate anarrangement 1n which sole-blanks are fed automatically, from a supplyrece tacle, to a position in the clamping or workolding means of themachine, and in which these clamplng means and the mechanism for causingthe relative movements of the sole-clamp and the tools are actuated intimed coperation with the sole feeding means. The invention alsoincludes 'an arrangement in which the soleclamp has longitudinalmovements, .while the tools are revolved around the sole-c mp, these twomovements being combine 1n suelia manner that the point of engagement ofthe tools with the sole is always kept near to the center of revolutionoi? the' tools.

Other objects of the invention, and the features of construction bywhich they are attained, will be set forth hereinafter in connectionwith the description of the illustrated embodiment of the invention.

The preferredform of the invention is illustrated in the -accompanyingdrawings, in which Figure l .is a front 'elevation of a machineembodying the present invention, with a portion f the blank feedingmechan ism' broken avay; Fig. 2 is Aa right-hand side elevation of thecomplete machine; Figs. 3 and 4, taken together, constitute a plan viewof the entire machine on a larger scale than the preceding figures; Fig.5 is a detail plan view, on a still larger scale, showing a pvo'rtion ofthe 'blank feeding mechanism; 1g. 6 is a sectional view, on a vstilllarger scale, on the line 6 6 in Fig. 5; Fig.

The invention is illustrated as'embodied ina machine in whichsole-blanks or blocksoles are rounded, channeled and ooved to preparethem for attachment t t. e uppers .of McKay shoes, although sol' s forother types of shoes may be prepared by .the substitution -of properchanneling-or grooving tools. As is common 1n macbanesfor performingwork of this character, the illustrated embodiment of the invention isprovided with a pattern plate 30 upon which the sole-blank X restsduring the operation 5 of the .knivesi-thereon, the blank being clampedbetweenthe. pattern plate and an upper clamp member or plate 32. Theoperative instrumentalities or tools comprise a rounding knife 34, vachanneling knife. 36, and a grooving knife 88, which are caused totraverse the periphery of the sole-blank and cut the blank'to therequired contour and, at the same time, produce a channel and a groove.for the reception of stitches in the margin of the sole.

In order to automatically provide the machine with a flesh sole-blank atthe proper time, a supply offsuch blanks is held in a receptaclecomprisingf'ietical rods 40, 42, '44 and 46, between which a stack ofblanks is supported in a definite longitudinal position as shown inFigs. 2, 8 and 4. The rods 40 are fixed, respectlvely, to arms 48 and 50Awhich are mounted to swing horizontally about screws 52 and 54 on theupper`extremities'of a supporting frame 5 6. This frame has a base 58which rests on the* horizontal surface of a, table 60 constituting apart of the frame of the machine. Irl order that the blank receptaclemay be adjusted in length, in accordance with the length of thesole-blanks to be held by it, the base 58 is adjustably fixed on thetable by a screwl 62 passing through a slot in thebase.

The rods 40 engage the fore parts of the sole-blanks, and to adjust themto blanks of differentl widths, the arms 48 and' 50 are arranged to swinupon the screws 52 and 54,

as above descri ed. To fix thearms in adjusted position, a screw 64asses through a slot in the arm 48 and is threaded into the frame 56.The arm 50 is provided with a segmental gear 66 engaging gear teeth onthe arm 48, solthat-the arm 50 is simultaneonsly secured lin adjustedposition. Since relative adjustment of the arms may sometimes benecessary to provide for various styles of soles, the segmental gear 66is adjustably fixed to the arm 50 by means of a screw 68 (Figs. 2 and3).

The rod 44 engages the toe ends of the blanks, and in order that it maybe adjusted for variousV lengths and shapes of blanks, it is mounted'ona base 70 fixed to the base 58 by a screw 72 passing through a slot inthe base 7 0.-

The rods .42 .and 46 engage with the heel parts lofthe blanks andare'supported andv relatively I adjustable 'in substantiallyv the Same'manner as in .the case of the toe part engaging rods.. The rods orgages=44 and 46 determine the transverse position ofthe blankspreparatory to placing them on the pattern 30. I

The rods 40, 42, 44, 46 and a. pair of feed -arm and adapted to engage ablock 86 fixed ngers 74 and 76 form a magazine for supporting the blanksin a predetermined position for delivery to the pattern platt Thestackfof blanks in the magazine is supported, at the bottom, upon thetwo feed fingers 74 and 76 which serve to deliver them one at a timefrom the magazine to the pattern plate. These fingers are longitudinallycurved, square rods, which are slidably mounted in tubular arms 78 and80. A 75 spring 82, inclosed within each of the arms, presses thecorresponding finger outwardly, this movement being limited, however, bya stop pin 84 movable through a slot in the on the side of the arm, asshownvin Fig. 5. The lingers are normally in their extreme protrudedposition and stand, as shown in Figs. 3 and '4, directly beneath thelowermost blank of the stack.-

Each of the arms-78 and 80 is provided with a base flange 88, seatedupon a curved plate which is integral with the upper end of a lever 92,this lever'being pivoted to the frame of the machine at its lower end,so that the lever and the late may be swun toward and from the c ampingdevices o the machine. The plate 90 and the base flanges 88 are tonguedand grooved together, and have a screw and slot connection, as

shown in Fig. 5, -so that the arms may be 'caused to transfer the blanksfrom the bot- 105 tom of the stack to a. position upon the pat ternyplate 30. This swinging movement is produced by cam mechanism, and forthis purpose the lever92 'is connected, by. a link 94, with an arm 96which depends from one 110 end of a rock shaft 98 journaled on the frameof the machine. From the other end of the rock shaft an arm 100 projectsupwardly, and this arm carries. a cam roller 102 which cooperates with acam 104. The 1l5 cam is mounted on a camshaft 106, also journaled in theframe of the machine, and this shaft is rotated by means which wilLbedescribed later.

When the feed arms yare swung inwardly, the fingers 74 and 76 supportthe sole-blank' until they come into engagement lwith the edge of thepattern plate 30, as shown in Fig. 5, and thereafter the fingers remainsta tionary while the feed arms continue their 12aL lparticularly inFig. 3.

Thisslide is pressed forwardly by a spring is limited by the 110, whileits movement engagement of a in 112 with a recess in the slide. Duringthe last part of the feed movement of the arm 80, the slide 108 pressesyieldingly against the edge of the blank, and t'hus insures movement ofthe heel part of the blank to proper positioncn the attern plate.

f. 'Tiie forepart of `the sole-blank is positioned on the pattern plateby means shown These means com prise two gage fingers 114, in'the formof bell crank levers arranged to swing' horizontally about pivot screws116 on a frame 118. A spring 120, connecting the gage fingers, tends toswing them toward each other and the two fingers are. articulatedtogether by segmental gear teeth so that they swingsimultaneously towardand from each other. Their inward swinging movement is limited, however,b'y an adjustable stop 122, and this stop is adjusted in accordance withthe width of the sole-blanks to be operated upon.

During the rounding and channeling operation the gage lingers 114 areheld out of the path of movement of the operating instrumentalities ofthe machine, in the position shown in Fig. 3, and means are provided formoving them into operative position only during the blank feedingoperation above described. For this purpose the frame 118 is mountedupon a slide block 124 which moves in a horizontal slide-way 125 in thetable 60. A link 126 is pivoted to the bottom of the slide 124 andconnects it with the upper end of a lever 128, this lever beingpivotally mounted on the frame of the machine. The lower end of thelever is connected by alink 130, with a distance arm 132, and at thepivotal -connection between the link and the arm a cam roller 133 ismounted, this roller working in a cam path 134 on the side of a gearwheel 136. This wheel rotates on a shaft 138 and is actuated by meanswhich will be described later. Associated with the toe gages 114 is astop 142 which gages the toe end of the sole-blank. This stop isadjustably mounted on a slide 14.4 which has a screw and slot connectionwith the frame 118, and this frame also has a screw and slot connectionwith the slide 124. The. slide 124 has la uniform length ofreciprocation and at the end of the inward movement, the slide 144engages the pattern plate 30. The blank is gaged from the toe gage orstop 142, and this gage is alwaysbrought into a definite relation to thepattern plate 30. To provide for different sizes of patterns, the slide144 may be adjusted on the slide 124. The gage 142 is set slightly. backfrom the end of the slide 144- so that,'when the blank is in position,its edge will extend beyond the edge of the. pattern to allow for therounding operation.

After the toe gages are moved into engagement with the sole-blank, thesole blank is moved into position longitudinally against the stop 142 bya heel engaging arm 146 shown particularly in lFig. 4. This arm liesnormally in a position beyond and below the path of movement of the heelblank, but

is moved into operative position as soon as 1,48 which has bearings inthe frame of the machine. Directly below the arm 146 a second arm 152 ismounted on the shaft, and this arm is fixed thereto while the arm 146 isfree to swing, to a limited extent, upon the shaft. Avcoil spring 154connects the two arms and tends to rotate the arm 146 toward operativeposition. This relative movement of the arms is limited, however, by astop lug 155 which projects downwardly from the arm 146 into engagementwith the rear edge of the arm 152. One of the bearings 150 in which theshaft 148 turns bifureated, and a bevel pinion 156 is mounted on theshaft between the upper and lower parts of this bearing, being thusrestrained against vertical movement, but being keyed to the; shaft sothat it may rotate the latter. The pinion meshes with a segmental gear158,

on the lower end of an arm 160 which is f This arm carries a cam roller172 atits outer end, and the roller nieves upon a cam 174 fixed on thetable 60 of the machine. The cam is so shaped that when the arm 152 isswung inwardly by the mechanism above described, the roller rides up` onthe higher part of the cam, thusl raising the arm 152 and the shaft 148.whereby the arm 146 is raised into a osition in which its extremity mayengage t e end of the sole-blank wiwi/h is being positioned upon thepattern plate When the mechanism swings the arms bael Cit to normalposition, the descent of the shaft is insured by ay spring 176 coiledaround it beneath the bearing 150 and pressing against a collar 178fixed on the shaft.

To support the clamp plate when it is raised, and to press it againstthe sole-blank during the rounding and channeling opera tion, themachine is provided with means comprising a .hollow arm 180 which overhangs the pattern plate. As shown in Figs. Q and l, a slide 189 movesvertically in the end ot the arm and is perforated v really to receive aplunger 184;. A spring 18o inter posed between the slide and the lowerpart of the plunger7 :forces the latter downwardly, but this down rdmovemern is limited 'when the clamp is not in operation, by stop nuts188 on the upper l of the plunger. The plunger connected with the clampplate by two arms 1.90, eo that, when the slide 182 is in its lowermostposition,l

the pressure of the spring 186 is transmitted through the plunger andthe arms to the clam i )laf e and the latter pressed aeainst force topre pattern plate the the sole-blank with sui'iicient vent it fromshifting on the when subjected to the operation of knives.

In order thatihe cam plate majyv be automatically raised to receire asole-blank, the slide 152 connected with the forward end of a lever 192pivotally mounted in the hollow arm 180, and the rear end of this leveris connected with toggle arms 194 and 196. The arm 190 is integral withan arm 198 which is pivoted to the upper end of a link 200, and thelower end oi the link 'is pivoted to a. distance arm :202. At thepivotal connection between `the link and the arm, a cam roller ZOlmounted, and this roller works in a )ath in a cam disk Q06, as shown inFig. 9, t is cam disk being mountM ed on and rotated h r the cam shaft106.

A, feature of the operation. of the prefient machine resides in the factthat loiiigitmlinal moven'ienti are imparted to the sole-blank, and inorder to' permit the clamping means to perform such i'i'ioveim-ints, thearm 180 is mounted on a Slide Q08 which nieves in horizontal guidewalvsQ19 in the table G0 of the machine. Since the cam dislr 206 mustparticipate in these movements, it is splined to the shaft 106, as Shownin Fig. 9, and 1a i ieethQQS at the bottom oit the'elide 208, as.:

shown particularlj," in Fifr. i. The other ,eide of the rari: bar'1291icoperates with a gear Ywl'icel 21S-fh which meshes with teeth3f-iiv on the forward end of the arm 222 se as to ael'uate the lide:218. By the arrangement inet deecribedv` the two slides are inof'edequally and in unison, so that all tendency to cramp z 'oided. l

fne rack par 1s connected atene end, as sllown particularly in Fig'. S,with a lever 934 piroifgal at iis lower endY on the frame ol themachine, and to this lever is pivoted a link the other end of the linkbeing pivoted on the upper end of a distance arm it the pivotalconnection. between the link and the arm a cam roller 240 is mount ed,and this roller. as shown in Fig. 7, engagee a path in a` cam 2&2 fixedto the side oit the gear ln order that the amplitodo of il, moremeiil'simparted to the rack bar ma)Y 'be varied in accordance with the lengthof the sole-blanks which are being operated upon. thelever Z3/i isprovided with a series of holes into which the pi 'total connectionbetween the lever and the liiil: may be shifted.

The posts 210 support the pattern plate near its toe end and its heelend, and the disaance between these posts must be varied in accordancewith the length of the pattern piate om cases to keep the center of thelengtli of the pattern co-incident with the middle of the clamp plate.Accordingly, the posts are mounted on two slides 2li-t and 2.4.6. whichmore 'in a guideway Q18 at the top of the slide 218, as shownpartieularl)f 'in Fig. 16. The slides Q44 and i240 are provided withintegral racks meshing on o iposite sides with a pinion 252 mounted at te middle of the slide Q18, and this arrangement is such. that the slides244 and-246 are moi'able toward and vfrom each other, but are alwayeheld equi-distant from the i'niddle of the slide Q18. In order that theposts may he fixed in adjusted position. they are provided at theirlower ends with screwfthreaded reduced. portions 254` which )passloosely through openings in the slides 244: and i246 and engage nuts 256movable in T-slots formed in the slide 218, The posta are hexagonal incross-section in the middle por-- tions, and they may thus loe 'turnedwith a wrench to tighten the lnuts 256, and thus clamp the partssecurely in position.

The knives are revolved around the soleblank by means including anannular gear 260 whit-h turns in a recess in the top of the table Htl.As shown in Figs. ll). 1l :ind l?, a carrier, mrt 262, which may bedescribed the knife carrier is lived to the gear 260 and revolvedthereby o `er the top of the table (l0 and around the pattern plate. Tobrace the knife carrier, it is formed, at its inner extremity, withan'arruate bearingr member 264. which engages two segmental flangedbearing members Q66 fixed at the renter of the table. The knife Carrierat the b'eginning of the operation in a position with the knife 34-against the sole nt the point shown in Fig. YWhen operating' upon thesole, the knife rarrier makes a comy plete revolution from the pointshown in i edge of the pattern Fig. 5, around the sole and bai-k to thispoint. After complete revolution of the knife carrier, the longitudinalreciproeation of the pattern slide 218 carries the blank past the .pointillustrated in Fin'. 5. after the knife 34- has come to a rest. :indthen returns it to this point` again to give an over-feed of the blankand to make a smooth joint at the finish. i

' The knife carrier 262 is provided with a Quideway Q68 in which a slide270 moves horizontally. This slide forms partei a framework whirl) maybe desrribedas the knife-support. An overhanginn' uien 27;? risesintegrally from the slide 270 and snpn ports a knife-bloeit 271. Thisblock is pivoted on the knifesupport at its upper end by e pivoty srrew276 threaded in the end of the arm 2?2 and havingV n conical lower endengaging n eonieal reress in a lug; G73 Iun the knife-bleek. The lowerend of the bloek is similnrly mounted on pivot 280.

The horizontal movement of the knife support is providedin order that tle knives may be moved inwardly and.- nutwardly to ronform to the vontourof the putt-ern plate, and this movement is regulated by the engagementwith the edge of the pla r. of a follower 282 which is mounted ai thelower part of the knife-block and provided iii/ith a rounded suutace asshown in Fig. l5. for engagement with the pnttern plate. The plate isdivided into lippe-ianfl lower portions and 283, the lower 'p ion onlybeinex engaged bythe follower rlhis division of the edge is provided inorder that the rhannelinn and grooving knives may be guided. to someextent, independently of tlaf.- rouniing knife, whereby the distance of:he channel and the groove from the rounded outline of the sole insg/ bevaried in different parts of the sole, es is usually7 desirable, therounding knife being` independently guided by the upper part 284 of theedge of the pattern plate. To permit this independent 1novenient of theroundingknife, the shank 288 ot' the knife is arranged to slide in edovetailed guideway in the upper surtare of the follower 282, and it ispressed outwardly and into engagement withthe pattern plate by it spring290. Aerordingly, the rounding knife is held in engagement with thesurface 528+L on the pattern plate regardless of the movements of thefollower'QSZ and the knife-block.

As shown particularly in Figs. 1l and 14, the channelingV knife 36 andthe grooving knife 38 are provided with horizontally disposed Shanks ofdovetailed cross-section, which are adjustably clamped in the splitlower ends of two slides 292 and 294, rlhese slides move vertically in adovetailed guide- Way formed in front of the knife-block 274, byremovable bearing members 296. The knives may be adjusted horizontallyupon loosening the rlemp srrews 298 by which the shanks of the. knivesare fixed in the knife slides.

To limit the depth to which the channeling and growing' knives eut intothe soleblank, a presser foot 300 is arranged to bear upon the uppersurface of the work in advance of the channeling knife, this presserfoot being secured to the front of the knife slide 292 by n screw andslot connection, as shown in Fig. 11, so that it may be adjustedvertically. The presser foot directly sustains the slide 292 and thechannelingr knife. and, in order that it may also support' the, slide2.9i and the grooving knife, e plate 302 is adjustably fixed' to thefront of the slide 291. this plate havingA a portion which werhangs andengages the upper end of the presser foot. us shown in Fig. ll. Thisarrangement is such that. the grooving knife may be raised from theWork, by means hereinafter described, without raising the channelingknife, this being desirable in some eases where the groove isinterrupted ai the toe end ofthe sole while the Channel is formedrontinuously.

'-h of the knife slides is provided with an upwardly projecting stud304, about which is coiled a spring 306 tending to force the slidedownwardly and hold the knife in engagement with 'the work. The heads308 of the studs limit this downward movement,

where there is no work beneath the knives,

318 is coiled around each of the studs, one end of the spring beingattached to the corresponding arm 3l2 and the other to the spring drum.The drums are mounted 1n sleeves 320 forming parts of the knife carrierand are fixed therein by set screws 322. By rotation of the spring drumsin the sleeves, the tension of the aprings may be adjusted required. Thesprings tend to rotate the studs and swing the arms 312 in a directionto press the slide 270 toward the center ot' the machine, and therelation of' the arms and the links is such that the mechanism tends tocompensate for the diminish- 1.5 \ing tension of the springs as theslide moves inwardly, so as, to maintain a substantially uniformpressure of the follower against the l pattern late. In or er to liftthe knife slide 294 vand the grooving knife from the work when nec-Vessary. a yoke-shaped member 321(` is fixed crank leiter which ispivoted at. 330 on the The other2 arm 332 of the bell crank leverprojects` arm 272 of the knife support.

downwardly and rearwardly and is provided with a rroller 334 which restsbeneath a flanged `bar 336. This bar is fixed to the upper end of aplunger 338 which slides vertically in a bearing in the knife carrierand projects downwardly into the space beneath the annular gear 260, asshown particularly in Figs. 10 and 13. A cam roller 340 is vmounted onthe lower end of the plunger 338, and this roller cooperates with aflanged cam 342 of Figs. 3 and 13, which is mounted on the table 60beneath the gear 260. This cam is so located as to be engaged by theroller 34.() when, in the rotation of the gear 260, the grooving knifereaches the toe portion of the sole. The portion of the toe not actedupon by the grooving knife is indicated on the finished sole shown inFig. 4f. lVhen the cam is so engaged. it depresses the cam roller andthe plunger which. in turn,. cause the bar 336 to depress the roller334. and swing the bell crank lever in a direction to press upwardly onthe screw 32), and thus raise the yoke 324 and the knit'el slide 294 anddisengage the grooving knife .from the work. Owing to the yokc-shapc ofthe mem'A -ber 324. and'to the location of the screw 326 near thepivotal axis of the knife-block. these connections do not interfere withthe free swinging of. the knife block to conform to the outline of thepattern plate. and the connections between the bell crank lever and theplunger 338 are such as not to be aifc-.ffted by the sliding movementsof the knife support.

Some mamiacturcrs continue the stitching around the toe of the shoe.which case the grooving'kmlfe is not rendered inoperative at thatportion of the sole. In order that the grooving knife may not beaffected by the cam 342,\tlie cam is secured to the table 60 by a screwand slot connection 341 so that it may be moved radially out of the pathof the roll 340 to the position shown in Figs. 3 `and 10.

In the case of some soles no channel is produced at the heel extremityand, accordingly, it is desirable when this part of t e sole is reached,to raise both the ychanneling and groovin knives out of operativeosition. Accor( ingly, meansare provide for raising the channelingknife, these jmeans being in every substantial respect identical withthose employed for raising the grooving knife and comprising a plunger344 located alongside the plunger 338, as shown in Fig. 13, and providedat its lower end with a cam roller 346. The roller 346 does not extendoutwardly as far a's theA roller 34()y Q however as shown in Fig. 10. sothat it is never affected by hc cam 342. second flanged cam 343 (Fig, 4lwhich extends am gularlybelow the annular `gear 260 through- `out theportion which controls the actior of the knives on'lthe heel portion ofthe sole. acts on the roll 346. so that the channel and groove arediscontinued `at this time. as indicated on the sole illustrated in Fig.4. In thisway the machine may be arranged to automatically interrupteither the groove alone. or both the channel and the groove. as may benecessary in the production of the particular kind of sole which isrequired. 100

`In some classes of work the cam 342 mav be moved out ofA ilu path ofthe roller 340 so that both channel and the groove will be made on thetoe portion of the sole. In turn work. cams 342 and 343 would berendered '105 inoperative, so that a channel would be` fomed around theentire peripheryoi the so e.

To permit the operator to retract the knivesv when changing the patternplate. or

at. any other time when it may be desirable.

manually operable means are provided for this purpose. as shownparticularly in Figs.

.Il hand lever 350 is pivoted loosely on thc stud 348 and provided witha plunger 359.

ot' which the lower extremity is adapted to coiiperate with the teeth ofthe disk 354.

.\ spring 360 presses against a button 362 at the upper end of theplunger and holds it no1-mall)- in inoperative position. but when theknives are to bc retracted. the operator presses upon thi,l button andthen rocksl the lever. thus rotatingthe gear 350 and retractingz theslide 270. In order to retain the 13( slide in retracted position, thehead of the stud 348 is provided with ratchet 'teeth 364, and the handlever 356 carries a springpressed latch 36() which cooperates with theratchet teeth. This latch may be released, when necessary, by a trigger368. It will be noted that the ratchet teeth 364 prevent thc knife.carrier from moving toward the pattern, but they will permit the carrierto 'be pushed lrack if the pattern comes into enga rement with it. l

Phe annular gear 260 is rotated by engagement with apinion 370 (Figs. 4,7 and 8) which is fixed on the upper end of a shaft 372. The. lower endof this shaft turns in a bracket 374 on the frame of the machine and isprovided with a bevel pinion 376. This pinion meshes with a pinion 378,which is mounted loosely on a Ydrive shaft 380. This shaft is rotatedconstantly and it carries a pinion 388 which drives the gear 136, andthrough it the two cam shafts of the machine, by the connections abovedescribed. These cam shafts perform one rotation for each com lete cycleof operations of the ma-A chine.

he revolution of the gear 260 and the parts carried by it must beintermittent, and, accordingly, the pinion 378 is connected with theshaft 380 by a clutch pf the well-known Horton type. The construction ofthis clutch need not be described, but it will 'be understood that, itsoperation is such that it may be held out of operation by the action ofa detent 384, thuspermitting the shaft 380 to rotate without driving thepinion 378. Then the detent is moved out of engagement with the clutch,the pinion 378 will' be rotated until the detent is again moved intooperative position. The detent forms the lower end of-a lever pivotedupon the bracket 374 and carrying a cam roller 38(3 at its upper end,and the roller works in a cam path in the cam 242, this path beingformed to throw the Horton clutch into and out of operation -at theproper times in a cycle of operations ot' the machine.

In order to actuate the drive shaft 380, itI

is connected by skew gears 390 with a power shaft 392. The power shaftcarries a pulley .304 by which it may be connected with any suitablesource of power, and the pulley is connected with the shaft by clutchmechanism of any ordinary or suitable form, controlled-by, a hand lever396 at the front of the machine whereby the machine may be thrown intoand out of operation.

After the completion of the operations on a sole-blank, it is removedautomatically from the pattern plate and discharged from the machine 4bymeans which will now be described. A rock shaft 398 is journaled ver-`tically in the frame of the-machine and projects through .the table 60.At the upper end of this shaft an arm .L00 is fixed. and this arm has afo"wardly bent extremity 402 provided with a sole gripper', which isshown position. The lower gripper jaw is in the form of a slide 412which has a dovetailed connection with the part 402 (see Fig. 9). This,slide is pressed forwardly 'bya coiled spring 414, so that it tendsto-assume the position of Fig. 19 in which it is beneath the upper jawso that a sole may be gripped between the jaws.

The slide 412 has at one side an upwardly projecting sleeve 416 in whicha springpressed plun er 418 is vertically movable, this plunger'eingprovided with a pin 420 which projects laterally through a slot in thesleeve. The arm 408 has a cam-like flange 422 which projects laterallyinto the path of movement of the pin 420. When a sole is to be removedby the ejector, the arm 400 is swung forwardly and the parts of thegripper are then in the position of Fig. 19. The slide 412 is brought bythis swinging movement into engagement with the heel end of the patternplate, as shown inl Fig. i8, and since the slide projects beyond theupper jaw, it is caused to have a rearward sliding movement by thisengagement before the upper jaw has reached the sole on the patternplate. This rearward sliding movement causes the pin 420 to ride overthe flange 422, thus depressing the arm `408 and raising the upper jaw,and by the continued swinging movement of the arm 400, the upper jaw isbrought into position above the sole. Finally, by the continued movementof the Slide, the pin 420 is moved beyond the rear end of the ange 422,thus disengaging it and permitting the spring 410 to force the upper jawdown against the sole, as shown in Fig. 18. The ,arm 400 then swung backagain. and during the first part of this movement the upper jaw dragsthe sole with it, while the lower jaw or slide is projected again by thespring 414, so that when the upper jaw has been moved entirely away fromthe pattern plate, the

sole is gripped between the two jaws. In

this manner the sole is carried to the position of that shown atthe leftof Fig. 4, but when the arm 400 reaches its normal position. the beveledrear extremity of -the arm 408 is brought into engagement` with a tripdevice 424, which depresses the arm and opens the gripper. thuspermitting the sole to fall into a recess 4,26 in the table 60 fromwhich it may be removed.

the type wheel in the In order toit-impart the'ncessaryfrockingmovements tothe shaftBQS-'by which the-n ejector 'arm isactuated as'above described, this shaft is provided, as shown in Fig. 8, with apinion 428 which meshes with a segmental gear 430 on thel lower end ofan arm 432. This arm is mounted to swing' on a stud 434 on the frame ofthe machine, and a second arm 436 integral with the arm 432, carries acam roller 438 which works in a cam slot formed in the face of the gearA170.
